AUTOMATIC LUBRICATING DEVICE FOR THE RING AND THE TRAV IN RING SPINNING OR DOUBLING FRAMES OR THE LIKE Filed Jan. 12, 1934 Patented June 9, 1936 .THELIKE I Carlo Schleifer, Novara.

' It has already been proposedto lubricate the rings of ring spinning or doubling frames and the like with the object of facilitating the move,- ment of the traveller, because it is well known that the friction of the traveller on the ring not only produces considerable 'wear of these parts, but also occasions irregular tensions in the yarn which frequently cause it to break.

Among'the numerous lubrication devices hitherto proposed, those which, while possessing seriousdisadvantages, are the most nearly suitable, comprise a wick fed by a reserve of iubri-" cant and leading up to the surface of the ring to be lubricated where it frequently extends over large zones and is in direct contact with the traveller., For example, this wick is lodged in deep grooves hollowed in the internal surface of the ring in contact with the traveller. These open grooves are in general supercharged with lubricating material which spreads constantly over the surface to be lubricated, both during the traverse and during periods of rest of the traveller, and consequently it accumulates during the periods of rest of the machine.

When themachine is restarted after a relatively long idle period, the lubrication is considerably in excess of requirements and may cause the yarn to be soiled. Further, metallic particles due to the wear of the traveller, and

also dust, will accumulate in the said grooves and upon the wick containedtherein. Consequently, these open.groves form receptacles for dirt and are the main cause of the yarn becoming soiled.

Further, in many of theseknown lubricating devices, the lubricantreservoir is closed by a felt member in contact with the surrounding air and which collects dust and any dirt, so that it ring rail clean.

Now the object of the present invention is to provide a lubricating device ofthe above mentioned type which comprises none of the above mentioned disadvantages and effectively ensures that the lubrication will be obtained automatically and exclusively during the traverse of the traveller. I

According to the present invention, one or more internal ducts are formed in a tangential direction in the body of the ring, in each of which holes is lodged a wick, the ends of which dip into a reservoir of lubricant while each tan-' gential hole communicates .with the surface to be lubricated and which is touched by the traveller through one or tially radial holes through which the lubricant 'taining lubricant. The tangential more small and substanbut is removed by the traveller when it passes over these holes.

Some embodiments of the subject of the invention are illustrated simply byway of example in the accompanying drawing in which:-- 1 Figures 1 and 2 show in detail to an enlarged scale and in cross-section and plan view respectively a portion of the ring with the lubricating device.

Figures 3 and 4 show in vertical section and in plan view respectively the assembly of the ring and of the ring rail.

Figure 5 is a vertical section of a modification. a l

According to the present invention (Figures '1 and 2) a hole 2 is formed in a tangential direction in the body of the ring I substantially .at half its height; in this hole is lodged a wick 3 the ends of which dip into a reservoir 4 contowards the inner surface of the ring I, touched by the traveller 5, through one or more small and substantially radial holes 8, which are absolutely devoid of any filling material. The lubricant supplied by the wick reaches the small holes 6 but does not flow from these holes successively. Only when the traveller 5 moves along the ring and rubs against the terminal orifices of the small ducts 6 will it remove by mechanical means the particles of lubricant which are'sufllcient for lubricating the traveller and the traveller then itself distributes this lubricant over the entire surface with which it comes into contact.

When the movement of the traveller ceases, the lubrication also ceases automatically. When work is restarted, even after a long idle period, there is no danger that the ring will have been excessively lubricated or soiled in any way in the interval, and any soiling of the yarn is thus avoided. Similarly, all other causes of soiling'the yam mentioned above and which areproduced by the known devices are avoided, because in' the present case the wick is completely protected and is never touched by the traveller.

The ring I instead of comprising one single tangential hole 2 with the corresponding wick 3, may comprise a illustrated in Figures 3 and 4 this lubricating arrangement is duplicated.

The reservoir 4 containing lubricant may be provided in the by the split ring 8 in which is inserted the ring I number of holes. In the example,

hole 2 leads which has to be lubricated,

ring rail 1 and may have the shape of an annular receptacle and be protected T lubricant and an air vent H".

with the object of locking it in place on the ring rail by means of the usual. screws 9.

In the ring 8 is provided at least one holde 8' for the introduction of the lubricant.

The reservoir 4' for the lubricating material, instead of being in the ring rail, may be provided in a mounting ring I 0 for the ring i as shown in the modification illustrated in Figure 5. In this case'the ring I is provided-with a yoke ll serving to cover the reservoir and in which is provided at least one hole i l' forthe introduction of the The ring may be locked in place on the rail in this case by means of screws 9 in the usual manner.

It is moreover obvious that the invention is in no way limited to the precise arrangements described and illust'ratedbut that without going.

outside its scope, it may undergo any modifica- ,tions that circumstances or the, requirements or practice may cause to be considered necessary or advantageous.

What I claim is:-

1. An automatic lubricating device for the ring and the traveller in ring spinning and doubling frames comprising a lubricant reservoir, a passage in the ring having open ends, a wick completely f l the passage and having its free ends extending fromvthe open ends of the passage into to the ring rail.

said lubricant reservoir for absorbing the lubricant therein by capillary attraction and wholly unobstructed and radial ducts in said ring extending from the e and terminating at the surface of the ring in contact with the traveller whereby lubricant is supplied to said surface, said reservoir being located below and said ducts substantially in the plane of said passage.

2. An automatic lubricating device for the ring and the traveller in ring spinning and doubling frames, as claimed in claim 1, wherein the lubricant reservoir is provided in a hoop carrying the ring, a separate reservoir being provided for each ring.

, 3. An automatic lubricating device for the ring and the traveller in ring spinning and doubling frames, as claimed in claim 1 wherein the lubricant reservoir is composed of a chamber formed in the ring rail, the said chamber having a cover whereby the ring is secured to the ring rail.

4. An automatic lubricating device for the ring and the traveller in ring spinning and doubling frames, as claimed in' claim 1, wherein the lubricant reservoir is composed of a chamber formed in the ring rail, the said chamber having a cover 25 integral with the ring whereby the ring is secured CARLO SCHIEIFER.
